[Trexmaster]

I can confirm as the person who was helping him (I also got rolled back, but, I traded a few times, so my losses weren't as severe.)

He got those two black books (magical star, shine sword), and was around level 57-58 when the server died.

As for getting that much exp in that much time--it was over the course of roughly 4~ hours (non-stop mind you) and we had nearly an entire training day, followed up by a high-level crazy dungeon.
